You can even attach to the same session from multiple terminals by using -x instead of -r. You can specify which session you want to reattach to by typing the desired screen session's identifier after the -r. Typing screen -ls will show the running screen sessions on the current machine. Detaching from the screen session works just as before. Now, within the single screen session, I can switch back and forth between the windows with Ctrl+a, p and Ctrl+a, n, respectively. Then I hit Ctrl+a, c to start a new window within screen, log into the other machine, and start the second thread. I start my screen session as before, then start the first thread. I want to split my script into two "threads" that will run simultaneously on two different machines (in half the time, obviously). A few hours later, I want to know how my script is doing, so I log into my machine (via login from the outside), type screen -r to reattach to the screen session, and there is my script, just as I left it, busily munching away at my data the whole time. I press Ctrl+a, d to detach from the screen session, then I log out of my machine and go home. I open a terminal, type screen to start a new screen session, and start my processing script. I want to process some data, and I know it will take my machine several hours to complete this process. ![]() You can even have several terminals ( windows) open within the same screen session and switch between them easily. This means the session will continue to run even if you are disconnected, and you can even explicitly "detach" from a screen session and re-attach again later (even from somewhere else!). You can use screen to create a persistent terminal session. you can't see what's happening) or even killed. Everything you were working on that you hadn't saved is lost, or the script process you had running is orphaned (i.e. As you're working, your internet connection is suddenly reset. Imagine the following scenario: You're at home, and you would like to use your home internet connection (DSL or whatever) to log into CoLi to check your email, process some data with a script, or whatever else. To connect from the outside directly to a cluster node you could use this: ssh -t ssh jones-6 If you would like to run compute jobs, please use the compute cluster machines: For looking at your email box, you can also configure your email client at home. Use: ssh -X then start the application, script of whatever you want to use. If you have a Linux machine, this is quite easy. (If it's your first time you may confirm the connection to this server once.)Ī more convenient approach may the use of an graphical ssh manager like If you have a Windows machine, you can open an Command Prompt or Windows Powershell and connect to LST network with: ssh then start the application, script of whatever you want to use. ![]()
